SACK FILLING AND SEWING MACHINE.

$PECIFIGATIO'N forming part of Letters Patent No. 597,075, dated January1 1, 1898.

Application filed February 8,1896. Serial No. 578,620, (No model.)

To aZZ whom it may concern.-

Be it known that I, ARTHUR T. TInnwELL, a citizen of the United States,residing in Chicage, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement in Sack Filling and SewingMachines, of which the following is a specification.

My invention relates to improvements in machines for filling sacks orbags with "arions materials and sewing up the mouths of such sacks orbags after they are filled; and

' my invention relates more particularly to improveinents upon the sackfilling and sewing machines shown and described in my Letters Patent No.539,455, of May 21, 1895, and in' my pending application, Serial No.541,865, filed March 15, 1895.

My present invention or improvement consists, in con nection with abag-filling mechanism, of a sewing mechanism, a series of openin g andclosing movable sack-holders, an endless recurringmrack upon which theholders travel to convey the sacks or bags from the filling-station tothe sewing-station and to the discharging and receiving stations, and annp-and-down movable bag-shaking device engaging the sack-holder, so asto shake the sack from its mouth or top edge, of a movable bumper orsupport adapted to strike or engage the sack at its lower end in orderthat the material in the sack maybe settled, compacted, or compressedsimultaneously from both the upper and lower ends of the bag. I

find by experiment and practice that by combining with the fillingmechanism and other parts a shaker that operates to move the bagholderup and down, and thus shakes and stretches the sack from its mouth ortop edge, and a bumper or support for the lower end of the sack to restupon or strike against as it is being shaken or lifted up and down bythe shaker at the top, the material in the sack may be much more rapidlyand perfectly settled and compacted in the bag.

Another feature of my present invention consists in combining with themovable bagholders the track upon which they travel, the chain or othermechanism for propelling the holders along the track, and the sewingdevice or mechanism, a thread-holding device provided with a feed deviceor mechanism for the thread, which feed device is set in operation bythe sewing mechanism itself or simultaneously with the sewing mechanism,and a friction-clutch or equivalent mechanism for gradually setting inoperation or communicating motion to the sewing mechanism, whereby thenecessity for suddenly stopping and starting the sewing mechanism and ofhaving it positively geared to start and stop at fixed intervals inrespect to the movement of the bag-holder along its track and in respectto the opening and closing of the threadholder is obviated. By thismeans I materially add to the durability of the machine and also causeit to run much more smoothly and easily and without shock or strain tothe sewing mechanism.

Another feature of my invention consists, in connection with the fillingmechanism and sewing mechanism, in the series of opening and closingsack-holders and the track and mechanism for moving them along thetrack, in providing a short guide or guard along the track, which isengaged by a pin projecting from each of the holders near the front endthereof for the purpose of compressing or keeping the holder closed atits front end until its rear end emerges from the guideflanges of thetrack, which hold the holder closed, thus preventing the front end ofthe holder from slightly opening and letting the filled sack sag downbefore fully reaching the position for discharging the sack.

My invention also consists in the novel construction of parts anddevices and in the novel combinations of parts and devices herein shownand described, and more particularly specified in the claims.

In the accompanying drawings, forming a part of this specification, andin which similar letters of reference indicate like parts throughout allthe figures, I have shown one construction and which I believe to be thebest construction of machine now known to me for reducing my inventionto practice.

Fig. 31 is a detail view of partshereinafter to be described, and Fig. 32 is a detail View of the clutchmechanism of the sewing device.

In the drawings, A represents the frame of the machine, and A are wheelsor casters upon which the frame is mounted to adapt it to be moved abouton the dock or warehouse where the machine is used to bring it inposition for connection with various elevatorspouts or otherspouts orbins from which the material to be sacked is to be delivered to themachine.

A is an electric or other motor mounted on the movable frame of themachine for supplying the power necessary for driving it in thedifferent positions where it may be placed.

B is an endless recurring-track on the frame of the machine, along whichthe series of opening and closing movable sackholders D D are moved orconveyed from the sack filling and measuring device E, shaker F, andbumper F to the sack-closing device G and printing device H, thence tothe sewing device K, thence to the discharging device M, thence to thesack-receiving station X, and finally back again to the filling device.Along this track B the movable sack holders are conveyed, preferably bya number of separate .conveyers or moving devices adapted to engage theholders, the same being preferably a power-driven endless conveyer orchain 0, a supplemental power-driven endless conveyer or chain 0', and ahand-operated conveyer or wheel C The track B isfurnished with sideguides or flanges Z7 Z2, projecting upward from the track and adapted toengage the two opposite side edges of the holders and thus keep the sameclosed, these guides or flanges having a space between them equal to thewidth of the holder when it is closed. The track B is also furnishedwith a wide slot or open space 17, extending from the sack-receivingstation X, where the holder is open to the device for closing theholder, and with a narrow slot 12 extending from the position where theholder is closed to the position where it is again opened to dischargethe filled and sewed sack. The guides or flanges 29 1) preferably extendonly part way of the track B-thatis to say, along that portion of thetrack where the hold er is held closed by said guides or flanges andalong the portion of the track at the sack-receiving station X to guidethe movement of the open holder along the track when it is being movedby the hand of the operator who puts the sack into the holder from thepoint where it is released by the conveyer O to the point where it isagain engaged by the conveyer 0 By thus making the track 13 plain orwithout guides or flanges for the holder at the curved portions of saidtrack I obviate all danger of accident from the holders binding on theguides as they are being conveyed or from one holder injuriously jammingagainst another.

The conveyer O, by which the series of holders D are moved along thetrack B from the holder closing device G to the sack receiving stationX, consists, preferably, of an endless-link chain traveling around thedriving sprocket wheel or pulley G the large sprocket wheel or pulley Cat the right-hand end of the machine, and the intermediate or idlerpulleys G O (3 0 Each of the holders D is provided on its inner sidenear its front end with hooks or projections 61 d adapted to engage thelinks of the chain conveyer Oalong that portion of the track where thepath of the chain 0 coincides with the path of the holder or track B.

From the sack-filling position to the sackclosing position the series ofholders D are conveyed or moved along the track B by the supplementalconveyer O,which is also preferably an endless-link chain and travelsupon the sprocket wheels or pulleys C O, located above the track B, thelinks of which are engaged by a hinged or pivoted hook cl, with whicheach of the holders D is provided at or near its front end and whichhook the operator lifts into engagement with the chain 0' after the sackhas been filled and the material settled or compacted therein by theshaker F and bumper F.

To hold the hook or projection (Z in proper engagement with the chain orconveyer C at the curved portion of the track or where the chain 0passes around the pulley C", I provide a guide or guard B, extendingaround the outer half-circle of the pulley C, there being a sufficientslot or space between this curved guard B and the conveyor-chain on thepulley C to accommodate or give room for the hook or projection (Z onthe sackholder D.

The supplemental hand-operated conveyor C is preferably made in the formof a wheel, and it is furnished with a hook, pin, or projection c on itsperiphery, which engages the pin or projection (Z on the holder, andthus conveys the holder around to a position near the sack-fillingstation. To keep the pin d of the holder in engagement with the pin 0 onthe conveyor 0, a guard 13*, extending around the outer periphery of theWheel 0 is provided.

Each of the holders D comprises two opposite side or long oars D D andfour short or end bars D D D D thesix bars being hinged together attheir ends, so that the holder may be opened and closed. One or moresprings d at one or more of the pivots of the holder serves toautomatically throw it open. Each of the holders is provided withclamping-jaws (Z (Z at its opposite ends and with clampingjaws (Z at itssides. The pivoted clamping-jaws (Z (Z are each provided withfrictionrollers d adapted to engage, respectively, the stationary camsor projections 11 b overhanging the track B, and thus automatically openthese clamping-jaws when the holder reaches the position. fordischarging the filled and sewed sack. Each of the clamping-jaws d isalso provided with a pivoted pawl or latch d to hold theclamping-jawopen against the pressure of the spring d by which theclamping-jaw is held closed. The latch (l is furnished with a spring dto hold it in position for engaging the clamping-jaw (Z when it is open.Each of the clamping-jaws cl consists of a long sectional blade havingnotches fl at intervals, secured to a rock-shaft 63 which has atorsion-sprin g (I to hold the cl am ping-j aw closed. Each of therock-shafts (Z is furnished with an upwardly-projecting arm (1, by whichthe clamping-jaw is opened and which is adapted to engage a stationarycam or projection bflsee Fig. 29,) overhanging the track I), and thusopen the clamping-jaw cl when the holder reaches the position fordischarging the filled and sewed sack. A

pivoted pawl or latch d engages a notch or projection (Z on therock-shaft of the clamping-jaw to hold it open, the pawl or latch 16being provided with a spring (Z To prevent the holder from beginning toopen at its front end before reaching the position for discharging thesack, I provide a short guide or guard B goverhangin g the track B, andwhich is engaged by a pin or projection (Z near the front end of theholder. When the pin (1 on the holder passes the guide or guard E therear end of the holder simultaneously emerges from between the sideguides b h of the track B, so that the holder is free to be thrown openby its springs d" (1 simultaneously at both ends. As long as the rearhalf or more of the holder remains between the side guides 19 b of thetrack B these side guides alone will efliciontly operate to keep theholder closed, and when the holder advances somewhat farther along thetrack B the pin d near the front end of the holder will engage the shortguide or guard B so that the holder willnowhe held closed at both ends,at the rear end by the sideguides Z) Z; and at the front end by theshort guide 13 engaging the pin (1 The pin or projection don the holderwhich first engages the chain carrier G is located on the front shortarm D of the holder adjacent to the chain carrier C, so that when theholder is shut from its open position to its closed position the mereact of thus closing the holder will throw this pin or projection 61 intoengagement with the conveyor 0, and thus cause the holder to begin tomove forward the moment it is closed. As the holder is thus advancedalong by the conveyer 0 its second pin or projection (1 which is locatedon the long side bar D of the holder, comes also into engagement withthe conveyer-chain C. The moment the holder reaches the sack-dischargingposition and is allowed to be thrown open by having passed the sideguides Z) Z) and the short guard B the pin or hook d on the short arm Dof the holder is automatically withdrawn from the conveyor O by the mereact of the holder opening, so that only one of the pins or hooks-via,the pin or hook cZ will pass between the curved guard B and theconveyer-ehain C as it passes around the pulley 0*. This prevents anydanger of interference or binding as the holder is conveyed around thecurved portion of the track. A pin or projection d on the holderprevents the holder from swinging under the line of the carrier-chain orthe pulley Cj by engaging the outer surface of the curved guard B".

As the holder D is in its open position when it is moved along the track13 into engagement with the carrier-wheel C it is only the pin (Z on theside bar-D that engages the projection c on the carrier-wheel O and thepin (Z in connection with the curved guard 13 performs the same functionat this end of the machine that it does in connection with the curvedguard B at the other end of the machine.

IIO

E is the filling device or spout through or by which the grain or othermaterial is filled into the sack.

The measuring device by which the quan-' bulk-measuring device, as shownin the draw ings. It comprises a measuring-chamber E", equal in capacityto that ofthe bag, a receiving-spout E and two valvesE Efithe upper oneseparating the measuring-chamber from the receiving-spout and *the lowerone separating the measuring-chamber from the. filling-spout E. Thesevalves "are alternately opened and closed by alever The shaker F, whichoperates to shake the sack from its mouth or upper edge by moving thesack-holder itself up and'down, is vi brated by revolving cams'f f onthe shafts ff through the connecting: straps or hangersf f The bumper F,against which thelower end of the sack strikes as it is being shook'orlifted up and down by the shaker F, consists, preferably, of anup-and-down movable platform or support. It reciprocates up and down on'asuitable guide F thebu mper being prefably provided with antifrictionwheels or rollers F to engage the upright guide F The bumper F is raisedto any required height and then locked or fixed in this position, sothat .the bottom ofthe bag will properly strike against it as itis'being filled from-the spout E and moved up and down by the shaker F.

It is thus fixed or locked in position by alatch or locking-pin Factuated by a spring F engaging one of a series of holes F in'theupright guide F. It is lifted to the required height by a chain orconnection F which passes over the pulley F on the sleeve F". A weight Fis connected to the chain F which partially compensates for the weightof the bumper and enables it to be more easily lifted into position foroperation. The bumper F is provided with a trip F which is engaged bythe bottom of the sack, so that the weight of the sack and its contentsagainst this trip as the bumper is being raised up will move this tripand thus release the springactuated latch or locking-pin F and thuspermit it to engage one of the holes in the guide F and thereby preventfurther movement of the bumper F. As the trip-lever F is thus operatedby the weight itself of the sack being filled the bumper will beautomatically stopped or fixed in proper position for properly bumpingor engaging the sack, whatever may be the precise length of the sack orthe precise point at which the mouth of the sack is clamped in theholder D. This feature is one of value in the practical operation of themachine, as the sacks always vary more or less in length, and because,even if the sacks were all of the same length, the

operator would unavoidably fix the mouths of the bags in the holders atmore or less varying points.

Motion is communicated to the shafts f'j",

by which the shaker F is operated from the shaft f through thebevel-gears f f 3 thereon.

engaging bevel-gearsf f on the shaker-op-- crating shafts f f". Theshaft f has fixed to it a clutch f and it is thrownin gear with theshaft n by a clutch-sleeve f, which is operated by a clutch-rod fthrough the lever f and a handle-bar or pull-rod f The clutch-rod f isalso furnished with an arm f that operates a sliding friction clutchsleeve f which engages the frictionclutchsleeve Fflto which thepulley orsprocket wheel F of the bumper-operating chain is secured As the clutchf f isa toothed clutch and the clutch f -F a friction-clutch,

that the operator by the first movement of the clutch-rod f l throws theshaker F into operation, and that the further movement of the sameclutch-rod throws the friction clutchsleeves f F into engagement witheach other, and thus causes the bumper F to be raised up against thelower end of the bag being filled until the weight of the contents ofthe bag against the tripF causesthetrip to moveand thus releasesthelatch or locking pin F when the bumper will be fixed thereby to' thestationary guide F 'As power is communicated to the bumper-raisingmechanism through a friction-clutch controlled by the clutch-lever inthe hand of the operator, the operator can, by exerting greater or lessforce upon the clutch-lever, cause the bumper to begin to be raised atany time desired as he feels the weight of the contents of the bag beingfilled, and as the bumper is being lifted the operator can at any momentdesired allow the weight of the bag and its contents to overcome thefriction between the faces of the friction-clutch f F". By this means,in connection with the trip F, the position of the bumper is alwaysunder the control of the operator. After the bag has been filled and itscontents sufficiently settled and compacted by the operation of theshaker from above and the bumper from below the operator moves theclutch-lever and the clutch-rod in the opposite direction and thusthrows the shaker-driving shaft f out of gear, and an arm on theclutch-rod f engages a lever what lighter than the bumper, so that thebumper will descend by its own weight after its locking-pin is releasedfrom the guide F The closer G or device for closing the sackholder 1)consists, preferably, of a reciprocating slide furnished withantifriction-rollers g to bear against one of the long bars D of theholder. The slide G is reciprocated in its guides g on the frame of themachine by means of a rack g, Fig. 10, which is engaged by a gear 9 onthe shaft g, which is operated by a chain passing around and secured toa sprocket-wheel g and which chain is attached to and operated by atreadle or lever G. A spring g Fig. 1, preferably a torsional spring,surrounding the shaft g" retracts the closing device G after the holderis closed and is conveyed beyond the closer and between the two sideguides l) b of the track 13.

Owing to the rough, coarse, fibrous fabric of which sacks or bags areusually made and to the more or less irregular surface presented to theprinting device by the sack and to the more or less irregular andyielding nature of the support afforded by the contents of the filledbag against the pressure of the printing device, I have found that itadds greatly to the success and efliciency of the machine as a whole tocombine with the other parts a printing device that operates in thenature of a stencil.

The stencihprinting device of the machine comprises a stencil H, mountedupon a reciprocating and slightly-rocking head or holder h, which iscarried by and pivoted to a reciprocating shaft 71, carrying theink-applying brush II. The brush-shaft 7L reciprocates bodily back andforth in a guide h The stencil head or holder h is f urnished with pins7r, that reciprocate in a guide h. A reciprocating slide 11 engaging thebrush-carrying shaft 71, moves said shaft and the stencil holder or headIt backward and forward in their respective guides 771 721 Thereciprocatin g slide 11 is furnished with a slot hiwith a curved end orshoulder 7&9 at its end,where it engages the brushshaft 7i, and thebrushshaft h is provided with arms 7L6 h, having slots h that engagepins it on the slide H Springs H are inserted between the slide H andthe stationary frame or box H to which the plates H are secured. Theguides 71 h are formed in or secured to the stationary plates H \Vhenthe slide H is reciprocated or moved forward, it pushes forward thebrush-shaft h and the stencil-holder it until the stencil is pressedagainst the bag X, as shown in Fig. 18, and until the brush-shaft 7Lreaches the limit of its forward movement and rests in the curvedextremity of the slot h", as shown in Figs. 18 and 18, this being doneby reason of the curve or shoulder h in the slot Jr in the slide Hiwhichengages the shaft h and moves it forward. The further forward movementof the slide H causes the brush-shaft h',which now rests in the curvedextremity of the guide or slot h? and thus prevented from furtherforward movement, to rotate on its axis by reason of the arm 72, on saidbrush-shaft h engaging the pin 71 on said slide H thus swinging orwiping the ink-carrying brush over the stencil and marking the bag byreason of the rotation of the brushshaft h. The wiping movement of thebrush over the stencil is repeated when the brush and its shaft makesits backward oscillation on the return movement of the slide H By thismeans I am enabled to print or mark upon the bag the requisitecharacters or data plainly and distinctly. The slide 11* is operated bya lever 7L furnished with a spring held or yielding pivoted arm h andwhich leveris connected to an arm G on the shaft G of the treadle G by aconnecting-link h.

The sewing device or mechanism K comprises, preferably, aframe or armK,attached to the frame A at one side of the track B and overhangingsaid track, a reciprocating needle K and a revolving looper K The needleis reciprocated by an eccentric or cam hi on the shaft K through thepitman-rod K, which is connected to an arm K 011 the rockshaft Kiwhichhas another arm K",connected by a link K with the slide K, to which theneedle K is attached. The loopcr K is revolved by a gear K on the shaftK through the intermediate gear ii, that meshes with the gear K on theshaft K of the looper. The shaft K of the sewing device is driven fromthe shaft N through a friction-clutch K K", the sliding clutch-sleeve Kbeing on the shaft K which has a bevel-gear K flwhich meshes with abevel-gear K on the shaft 1 The clutch-sleeve K" is operated to put thesewing mechanism in gear by a slide lji flwhich projects in the path ofthe holder D as it moves along the track B. This slide operates theclutch-sleeve through suitable connectin g mechanism, the sameconsisting, preferably, of an arm K on the slide K a connectinglink Kand a lever K, which is pivoted to a collar K on the clutch-sleeve K". Aspring K Fig. 24, moves the clutch-sleeve K in the opposite direction tothrow the sewing mechanism out of gear when the holder D passes beyondthe slide K. A friction-brake K engages the rear face of the bevelgear Kto stop the motion or momentum of the sewing mechanism as soon as theclutch K is thrown out of gear. This friction-brake is connected to theclutclroperatin g lever by the link K so that the brake is released themoment the clutch is thrown in gear.

K is the presser-foot. Its stem K is furnished with a spring K Thethread-cutter L L, Fig. 24:, consists of a pair of reciprocating knives,and the thread holder consists of a shoe or jaw L and a revolublethread-feed wheel U, which is geared to the sewing mechanism, so as torevolve and permit the thread to feed as long as the sewing mechanism isin gear. This causes the thread or chain to be fed or taken up as longas the sewing mechanism is runnln g and pre ICO IIO

vents entanglin g of the thread with the looper or other parts andobviates danger of breaking the thread or needle. The thread-cutterknives and the thread-holder devices are mounted upon reciprocatingslides L L which are furnished with pins or rollers L U, which engagethe holder D, so that the holder as it passes along will separate theseslides and permit them to be closed by their springs L L when the holderpasses. The threadholding shoe or jaw L is supported on independentsprings L on the slide L so that it may have a yielding pressure againstthe thread holder and feeding roller L In order to prevent the slide Kfrom closing or moving back to throw the sewing mechanism out of gearuntil the thread cutter and.

holder slides L L can close, I provide the slide L with a projection Lthat engages the arm K on the slide K and thus prevents said slide Kclosing in advance of the slide L Any suitable mechanism may be employedto gear the thread feeding and holding roller L to or with the sewingmechanism. The means I prefer to employ is shown in the drawings andconsists of an eccentric on the sewing-mechanism-driving shaft K, which,through a pitman or connecting-link L operates a lever L carrying a pawlL that engages a ratchet-wheel L on the shaft L of the roller L L is alocking-pawl, also engaging this ratchet L requisite feed movement maybe communicated to the thread or chain-stitch holding and feeding rollerL The filled and sewed sack discharging device M consists, preferably,of an inclined revolving spring supported platform. This platform M isattached to a sliding and rotatable SIM-3X76 M on the inclined shaft Mthe sleeve being supported by a spiral spring M surrounding the inclinedshaft. A spiral groove m in the sleeve causes it to rotate as itreciprocates. downward on the rod under the weight of the sack when itis dropped upon it by the opening of the holder D. When the springretracts, it returns the platform to position to receive another sack. Mis an arm to guide or hold the upper end of the sack until it is swungaround and discharged.

N is the main driving-shaft of the machine. Motion is communicated to itfrom the motor A on the frame of the machine through the belts N N andpulleys N N N N, and N pulley N being a loose pulley on thedriving-shaft and the pulley N the driving-pulley. Motion iscommunicated from the driving-pulley C to the shaft 0 of thedrivingpulley C of the chain conveyer C by means of the gear n 011 thedriving-shaft N meshing with the gear n on the counter-shaft n flwhichcarries a small gear 91 that meshes with a gear 91 on the shaft 11 whichcarries a bevelgear at, that meshes with a bevel-gear n on the shaft 0of said conveyer-driving pulley 0 Motion is communicated from theshaftBy this means the n to the counter-shaft at" through the spurgears 71 na. Motion is communicated from the shaft 91 to the shaft n carrying theclutch f for driving the shaker-operating shaft f by means of abevel-gear n on said shaft 11 which meshes with a bevel-gear n on saidshaft 71 One of the pulleys (J of the supplemental conveyer O is securedto this same counter-shaft n and is thus driven continuously.

Motion is communicated to the sewing mechanism K, as before described,through the friction-clutch K K", one member of which is carried by thedriving-shaft N.

The supplemental conveyer or wheel 0 is preferably operated by hand,this being conveniently done by means of a shaft 0 and carrying a bevelgear 0 that engages a bevel-gear C 0n the shaft of the conveyer 0 It isoperated by a crank 0 It will be observed that in my present improvement, wherein a frictional or yielding connection or frictionalclutch is interposed in the mechanism for communicating motion to thesewing mechanism from and by the movement of the traveling sack-holder,the sewing mechanism is stopped and started gradually and without suddenshock or dan- 1 ger of injury to the mechanism or interference with itsregular operation. In order to practically combine such frictionalclutch or yielding connection with the other parts and prevent danger ofbreaking the needle by engagement with the sack in cases where thefrictional or yielding connection in the sewing-maehine-drivingmechanism should leave the needle projecting across the path of the sackor of the next sack in the succeeding holder when the sewing mechanismstops I so arrange and combine the parts that the sewing mechanism isset into motion and its needle into vibration some little time beforethe sack reaches the needle and so that it will continue in motion somelittle time after the sack passes the needle. By this means allpossibility of the needle being broken by engagement therewith of thesack in the moving sack-holder is obviated, and to take up the surpluschain or stitching thus formed and projecting beyond the sack as fast asit is formed 1 provide the thread or chain holder with a revolvingroller or feed device. This prevents the projecting chain or stitchingfrom becoming entangled or interfering with the operation of the machineor needle.
